本文描述的Mobley型宽窗磁铁是安装在我所2.5MeV质子静电加速器中,为获取1ns脉冲束装置的一个关键设备。在加速器电压为1.5～2.3MeV、粒子能散度0.5％左右时,对H~+和D~+束可分别将10～15ns脉冲束压缩或0.9～1.1ns和1.3～1.5ns,靶上最佳束斑3×4mm~2。
The Mobley-type wide-window magnet described in this article is a key device installed in my 2.5 MeV proton electrostatic accelerator to acquire a 1 ns pulsed beam device. When the accelerator voltage is 1.5 ~ 2.3MeV and the particle energy is about 0.5%, the pulsed beams of 10 ~ 15ns can be compressed for 0.9 ~ 1.1ns and 1.3 ~ 1.5ns respectively for H ~ + and D ~ + beams, Good beam spot 3 × 4mm ~ 2.
